Title: Structure of injection screw
Inventor: MATSUURA MOTOO
IPC: B29C45/52
Filed: 1993-02-22
Abstract: PURPOSE:To prevent blocking of a screw head part caused by resin carbonization by installing more than one ring-shaped projected strip on the periphery of the cylindrical part of a screw head in the axis direction at regular intervals and installing more than one passage part, the circumferential position of which is relatively different between adjacent projected strips, on each projected strip in the circumferential direction at regular intervals. CONSTITUTION:A screw head 40 has a cylindrical part 41 having the same outer diameter as that of the shaft 23 of the measuring part of an injection screw 22. More than one ring-shaped projected strip 43 surrounding the cyrindrical part 41, the end of which approaches or contacts the inner diameter of a cylinder 21, is installed integrally on the cylindrical part 41 in the axis direction at regular intervals. More than one passage part which allows a molten resin to pass is installed at regular intervals. Each passage part 44 installed on each projected strip 43 is arranged so that its circumferential position is relatively different between adjacent projected strips 43. In this way, the backflow caused by the pressure increase generated in the circumferential direction of the screw head is prevented.

Title: Pallet stopper mechanism
Inventor: ANAI KENJI
IPC: B65G47/88
Filed: 1993-03-17
Abstract: PURPOSE:To moderate a impact when a pallet is stopped, and prevent bad influence on a mounting part by bringing a stopper into contact with the pallet before the pallet reaches a constant position, and stopping the pallet while applying opposite directional force to the pallet. CONSTITUTION:When a pallet 50 approaches a stopping position according to driving of a carrier conveyor 20, a sensor detects it, and a pallet receiving part 1 is raised by driving a cylinder 2. Thereby, the pallet 50 interferes with the pallet receiving part 1. The pallet receiving part 1 moves a slide base 5 in the A direction along a guide shaft 6 through the cylinder 2 by interference with the pallet 50. In this case, the slide base 5 receives inverse force to the moving direction by an action of a compression coil spring 7, and this force becomes large according to a moving distance, and the pallet 50 is decelerated. When the slide base 5 comes into contact with an absorber 8, an anti-back 12 is locked on a stopper block 4, and it is prevented from returning to a former position.

For judging the measured result, e.g. its class no. 4 is taken as a specified value, and a polishing cloth is replaced if it is exceeded. If the LPD measured value does not reach the set value, the polishing allowance of the semiconductor wafer is measured to determine the polishing force. If the polishing allowance is below the specified value, the polishing cloth shall be replaced.
